Create a basic_stringstream object. Use the specified initialString indicating the initial sequence of characters that this stream will access or manipulate. Use the specified modeBitMask to indicate whether this stream may be read from, written to, or both. Optionally specify the allocator used to supply memory. If allocator is not supplied, a default-constructed object of the (template parameter) ALLOCATOR type is used. If the ALLOCATOR argument is of type bsl::allocator (the default), then allocator, if supplied, shall be convertible to bslma::Allocator *. If the ALLOCATOR argument is of type bsl::allocator and allocator is not supplied, the currently installed default allocator will be used to supply memory.
